Rose plant-Meitonje variety

ABSTRACT

A new and distinct variety of rose plant of the Miniature Class is provided which forms abundantly and continuously highly attractive fully double blossoms. The blossoms are carmine rose in coloration. The plant exhibits a vigorous, compact and bushy growth habit, and is not particularly affected by cryptogamic diseases.

SUMMARY OF THE INVENTION

The new variety of Miniature rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the Meilucca variety (non-patented in the United States). The Meilucca variety is sometimes known as the Darling Flame variety. The male parent (i.e., the pollen parent) of the new variety was the Meifinaro variety (U.S. Plant Pat. No. 5,180). The parentage of the new variety can be summarized as follows:

    Meilucca×Meifinaro.

The seeds resulting from the above pollination were sown and 1,563 plantlets were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Miniature rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance on a continuous basis attractive fully double blossoms which are carmine rose in coloration,

(b) exhibits a vigorous, compact and bushy growth habit, and

(c) is not particularly affected by cryptogamic diseases.

The new variety well meets the needs of the horticultural industry for many usages. It is particularly well-suited for use as attractive ornamentation in parks and gardens.

The new variety has been found to undergo asexual propagation by a number of routes, including budding, grafting, cuttage, etc. The characteristics of the new variety have been found to be strictly transmissible by such asexual propagation from one generation to another.

The new variety has been named the Meitonje variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety described herein were two years of age and were observed during September while budded on Rosa froebelli understock and growing outdoors at LeCannet-des-Maures, Var, France.
